Answer:
no estoy segura como se debe responder
1 (x + 2y = -20) ----> x*2y= -20
-1 (x + 3y = -27) ----> x-3y= 27
(0) x + (-1) y = 7
C -3/2
Just multiply the second equation by -3/2
this will make the y term = -3/4y
so adding will eliminate the y terms.

Answer:
It's 65
Step-by-step explanation:
The reason is because the whole thing needs to be 180 right.
So one of the sides is 67
D would have to be 65 because of the angle and also it is less then F.
E is 48 because it is cut.
So the answer would be 65
I hope this helps!
